ONE rare lucid moment from a politician and we all get giddy with excitement.

Take note, Canberra: Australians are sick of one-dimensional, media-trained parrots who refuse to say what they really think.

That much became apparent this week when Cory Bernardi crashed Bill Shorten's media conference about the Liberal far right's "absurd obsession" with shutting down a school program teaching kids to respect people of different sexualities.

"At least I'm honest, Bill. You're a fraud," Bernardi quipped.

Shorten responded with the kind of on-the-spot honesty sorely lacking from modern Australian politics.

"No mate. At least I'm not a homophobe either, mate," he lashed back, with fire in his eyes and a steaming aura drifting off his spine as his skin turned green and his clothes shredded from his engorged body except for some remarkably elastic business pants that still somehow concealed his man-bits.
